Greetings, fellow data analysts!

How many different colors does a map need so that no neighboring areas have the same colors? Although it seems rather simple at first, this very question occupied mathematicians and cartographers for centuries. In 1976, Kenneth Appel and Wolfgang Haken discovered that four colors suffice. To answer this question, they applied a procedure which was developed by the German mathematician Heinrich Heesch in 1950 but only executable with the help of computers 26 years later. Most mathematicians feel that this

type of proof is awkward if not controversial because the humans doing the work can hardly understand it themselves. The four color set even gives cartographers a headache. Even though they know they only need four colors, which colors should they use for which region? Fortunately with management reports, your color schemes can be even more reserved. Most times, you only need two: a good and a bad color. This way, your reports are incredibly easy to understand. And when you use your computer for support, you don't even have to distribute the colors yourself.

DeltaMaster does it all for you. You already know how elegant these reports can be because you see them constantly in DeltaMaster. And seeing is proof. Today.

Best regards,
